Avon and Somerset Police detected the most offences in 2017/18 with nearly 200,000, while neighbouring Wiltshire recorded the least at just 1,191. Other forces in the top five for catching drivers were West Yorkshire, the Metropolitan Police, Thames Valley and Greater Manchester, according to research for the RAC Foundation. Dr Adam Snow, a lecturer in criminal law at Liverpool John Moores University, analysed Home Office data for England and Wales.
This showed 2,292,536 speeding offences were detected across England and Wales in 2017/18, up four per cent compared with the previous 12 months.
This means an average of four drivers were caught every minute.
In 44 per cent of cases, the offender was sent on a speed-awareness course, while a third attracted fixed-penalty notices.
Eleven per cent of offences were cancelled and one in 10 resulted in court action.
